Abstract

PURPOSE: To reset the movable mirror to the home position in a short time and enable correct photography to be obtained in continuous automatic exposure photography by engaging the kick-up pin secured to the movable mirror and bound preventing lever.
CONSTITUTION: A stopper 6 which defines the descending stop position of the movable mirror 1 installed oscillatably between a photographic lens 1 and image plane is provided and a bound preventing member 23 which so acts upon the mirror 1 as to inhibit the asecending of the mirror 1 near the stop position or in the descending stop position of the mirror 1. The member 23 is constituted by the movable lever which engages to the mirror kick-up pin 5 secured to the mirror 1, escapes to the outside of the oscillating locus of the pin 5 at the descending terminal part of the mirror 1 and again enters the oscillating locus at the arrival of the mirror 1 at its descending position.
